Imagine that every single car driver was a professional who went through years of training and had to be periodically tested through their entire career to prove they knew how to drive.
And the cars they drove had to be maintained to a very tightly controlled and monitored maintenance plan.
And the car had to be designed to incorporate every known practical safety device.
The key though, is that there is no such thing as “distracted” flying or someone having a bad day – it takes a substantial amount of effort to crash a plane (like 9/11).
And a party constantly monitored every car and explicitly gave them orders to keep them apart from each other and things they could hit and watched to make sure they did it.
And, on top of all that, imagine that every single time there was a car accident it got investigated by dedicated professionals and, as needed, the driver training, car design, maintenance plan, and controllers had all their procedures updated or fixed so that accident couldn’t happen again.
Then do that continuously for about 70 years. There would be surprisingly few ways left for you to have an accident.
Commercial aviation has had multiple years where there were *zero* fatalities around an entire country. Cars kill about 100 people a day in the US alone.
